SmartSDR DSP API
|
||
|
|
|
||
|
|
SmartSDR-DSP contains the source code for a wrapper, as well as an implemented example of a modem for any signal processing block that could be attached to a SmartSDR radio.
|
||
|
|
|
||
|
|
The implemented example uses the CODEC2 digital voice coder and FreeDV HF Modem developed and released by David Rowe.
|
||
|
|
|
||
|
|
The intention is that the API, defined by example, in the wrapper could be used to attach a PSK-31 Modem, or a RTTY modem,
|
||
|
|
or any signalling system to the radio. Provisions are included for multiple audio or I-Q baseband input or output streams.
|
||
|
|
|
||
|
|
Although originally intended for bi-directional signalling modems, the actual implementation could be expanded well beyond simple signalling to such things as noise-blankers or a skimmer, or any third party software that would benefit from baseband or audio stream access.
|
||
|
|
|
||
|
|
The API and the wrapper are "open" under GPL2, and therefore allow third party access to an otherwise "closed" software defined radio.
|
||
|
|
|
||
|
|
This interface, by using VITA-49 Ethernet packets for control, status and data transport enables an architecture where the
|
||
|
|
"MODEM" can be located inside a separate process inside the radio, on a separate processor attached to the network, or in a separate PC, particularly for development purposes.
